Title: Protection structure for absorbing ground displacement of buried pipe
Inventor: NASU TAKU
IPC: F16L1/038
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To provide a protection structure by which even if ground change due to fault displacement is caused by an earthquake or the like, the damage to a buried pipe can be reduced. SOLUTION: Plural protection pipes 11a, 11b for forming a protection structure 10 are installed on both sides of a buried pipe 3, and buried by back filling earth 2. The protection pipes 11a, 11b are needed to be bent for absorbing ground displacement, so a flexible pipe, or a resin pipe such as a polyethylene pipe or the like is used. The protection pipe 11a is provided with two slits with a depth two-third or less of the pipe thickness from the outside to the top side of a cross section. If lateral displacement is caused in the ground 1, the slit 12a is opened to deform the protection pipe 11a in a large scale so that the ground displacement is absorbed, whereby ground displacement is not transmitted to the underground pipe. If no ground displacement, the slit 12a is closed to earth pressure so that it is not crushed by earth pressure.

Title: Battery voltage monitoring circuit
Inventor: OKUBO YOSHITAKA
IPC: G01R31/36
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To suppress the unneeded consumption of a battery power supply and to prevent the deterioration of the battery by enabling a battery power supply switching part to electrically separate the battery from a battery voltage detection part when a device with a battery voltage monitoring device stops operating. SOLUTION: A MOS-FET 21 is inserted to, for example, the plus side of a line for connecting a battery 10 and a battery voltage detection part 11, a resistor R21 is connected between the drain and gate sides of the MOS-FET 21, and a resistor R22 is connected between an inverter 22 where a signal from a device side is inputted and the gate side of the MOS-FET 21. Then, when a signal from the device side is at a high level (the device is operating), the MOS-FET 21 is turned on and the battery 10 and the battery voltage detection part 11 are connected. When a signal from the device side reaches a low level (the devices stops operating), the inverter 22 inverts the signal to a high level and turns off the MOS-FET 21 and breaks the connection between the battery 10 and the battery voltage detection part 11.

Title: Correcting method for folder bridge
Inventor: NAKANO HIROYUKI
IPC: H05K3/22
Filed: 1993-01-19
Abstract: PURPOSE:To move solder forming a solder bridge on to leads by heating the leads bridged by the solder at high speed locally. CONSTITUTION:When voltage is applied to the feeding part 11 of a correction head 6, a heat chip 7 generates heat by its resistance. It is desirable that this heating should be performed at high speed. For example, it is so performed that the temperature may reach 280 deg.C within a second. Besides, it is desirable that leads or pads should be point-heated in a range of 0.01-0.20mm<2>, on this occasion. The heat chip 7 is positioned on leads 2 bridged by solder by observation with a with a microscope, etc. After that, voltage is applied to the feeding part 11, and the heat chip 7 is heated. By doing this way, the solder is separated and moves to the leads where it should originally be, and the solder bridge is corrected by the nature of solder that solder melted by heat generated by the heat chip 7 spreads and moves in a direction of higher solder temperature. Consequently, it becomes possible to move the solder forming the solder bridge on to the leads.

Abstract: PROBLEM TO BE SOLVED: To prevent a content in a container from oozing out by a method wherein two threaded members each having a hole communicating with a vent opening are provided at the center on the inner face of a cap, and a porous sheet is held between the two members. SOLUTION: Screw threads 3 to be screwed on a mouth of a container main body are formed on the inner face of a sidewall of a cap 1 and protrusions 4 are formed on the outer face of the sidewall to easily hold the cap 1. An upper threaded member 8 with a hole 7 leading to a vent opening 2 is projected from the center of the inner face of the cap 1, and a lower threaded member 9 to be screwed on the upper threaded member 8 has a hole similarly and a sheet mount 10 to hold an airpermeable sheet 6 between the downside of the upper threaded member 8 and the upside of the lower threaded member 9. The air-permeable sheet 6 is placed on the sheet mount 10 and fixed by holding it between the upper threaded member 8 and the lower threaded member 9.  Thereby, a porous membrane of the air-permeable sheet itself is prevented from breaking through fusing in the case the air-permeable sheet is fixed by thermal fusion bonding.

Abstract: PURPOSE: To form an air curtain in the communicating part and prevent the entry of pollution materials into insulator chamber by setting the amount of the gas to be blown into the vent pipes provided to the insulator chamber and the communicating part between the insulator chamber and dust collecting chamber at desired value.  
     CONSTITUTION: Gas introduced into an insulator chamber 9 through a lead-in pipe 11 flows down in straightening pipes 16, 17 and the gas introduced into an annular pipe 12 through a lead-in pipe 14 is discharged through a slit 13. Since the velocities of flow of both gases are independently controlled by respective valves 10, 15, the velocities of flow of the gases adequate for the perfect air curtain to be formed in the straightening pipe 17 may be selected. Because of this, the dust floating in the dust collecting chamber 3 of the insulator chamber 9 outlet is cut off by the air curtain formed in the straightening pipe 17 and is prevented from flowing into the insulator chamber 9. Hence, the surface of the insulator is kept sufficiently clean and the decrease in insulation performance may be prevented.
